Specification of Letters Patent.

Patented May 1, 1906.

Application filed December 11, 1905. Serial No. 291,323.

To on whom it may concern Be it known that We, WILLIAM H. MITCHELL and JOSHUA A. IsAMAN, citizens of the United States, residing at Aurora, inthe county of Hamilton and State of Nebraska, have invented certain newand useful Improvements in Gates; and we do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in swinging gates.

, and operated by said spring-projected latchbar to catch and hold thelatter and said gate in a closed or opened position.

With the above and other objects in view the invention consists ofcertain novel features of construction, combination, and arrangement ofparts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side view of a gateconstructed in accordance with the invention, showing the same in itsnormal closed position. Fig. 2 isa similar view showing the gate in anelevated position to permit the same to be swung over snow, ice, orother obstructions. plan view, and Fig. 4 is a vertical sectional viewthrough the automatically-operating keeper-plates on the latch-post.

Referring more particularly to the draw- .ings, 1 denotes thehinge-post, which is supported by suitable brace-bars 2 and is providedwith right-angularly-projecting side brackets 3. Secured in the brackets3 and in a suitable bearing-socket 4 is a vertically-disposed pivot-baror pintle 5, on which is slidably mounted the gate 6. Said gate isprovided with loop-shaped hinge members 7, by means of which it isslidably connected to the pintle 5. The gate 6 may be of any suitableFig. 3 is a top construction, the same being here shown as formed oflongitudinal horizontal bars 8, connected together at their ends byvertical cross-bars 9 and by segmental brace-bars 10.

The upper end of the pivot-bar or pintle 5 is slotted or bifurcated, andin said bifurcated upper end is pivotally mounted an operatinglever 12.The latter is connected at its inner end to'the extended upper end ofone of the segmental brace-bars of the gate, whereby an evenly-balancedconnection Will be had between said lever and the gate to enable saidgate to be raised squarely or perpendicularly upon the pintle-bar 5. Onthe outer end of the lever 12 is secured a frame 13, in which are journaled guide-rollers 14. To the inner end of the lever 12 areconnected laterallyprojecting guide-brackets 15, through which andaround said guide-rollers 14 are passed flexible operating elements,which are here shown'in the form of cords or cables 16. The inner endsof the latter are connected to a pivotally-mounted lever 17, the lowerend of which is pivotally connected to the inner end of aslidably-mounted latch-bar 15. To the lever 17 above and adj aoent toits pivotal connection with the latch-bar is connected one end of acoil-spring 19, the opposite end of which is connected to the outercross-bar 9 of the gate. The tension of the spring 19 is exerted tonormally project the latch-bar 18 to a locking position.

The cords or cables 16 extend from the guide-rollers 14 of the lever 12to supportingposts 20, which are located on either side and at asuitable distance from the hinge-post 1. The posts 20 are provided ontheir upper ends with guide-eyes 21, throu h which the cords or cables16 pass, the en s of said cables hanging down on the posts 20 in position to be conveniently grasped by an approaching driver or rider. Tothe outer end of the operating-lever 12 may also be connected a cord orcable 22, by means of which it may be tilted or rocked to elevate orraise the gate to the position shown in Fig. 2 of the drawings.

Adjacent to the free end of the gate 6 when the latter is in closedposition is arranged a latch-post 23, to which is connected an archedframe 24, in which are pivotally mounted curved keeper-plates 25. Theupper ends of the keeper-plates 25 are bent to extend upwardly in asubstantially vertical position,

the extreme u per ends of .said plates being curved inward y, as shownat 26. The lower ends of the keeper-plates 25 below the pivotalconnection of the latter are considerably nal ositions after the passingof said end of the atch-bar, thus holding the latter in confinementbetween said upwardly-projecting ends of the plates and preventing theening of the gate until sald latch-bar has een retracted.

Pivotally mounted on the supporting-posts are keeper-plates 27, whichare arranged in therpath of and adapted to be engaged by the latch-barwhen the gate is swung to an open position in either direction, therebyholding said gate open. The plates 27 are ivoted to swing in bracketsextending out from the post 20.

In operation to open the gate when approaching in one direction or theother one of the operating cords or cables 16 is pulled, which operationfirst rocks the latch-bar lever and retracts the latch-bar fromengagement with the keeperlates, after which a further drawing or puling of the cable 16 will cause the gate to swing to an open positionand the latch-bar 18 to automatically engage one or the other of thekeeper-plates 27 on the supporting-posts 20. When it is desired toelevate or raise the gate to permit the same to swing freely over snow,ice, or other obstruction, the operating-cord 22 is pulled downwardly,thus rocking the lever 12 and raising the gate, as hereinbeforedescribed.

Various changes in the form, proportion,

and the minor details of construction maybe resorted to withoutdeparting from the principle or sacrificing any of the advantages ofthis invention as defined by the appended claim.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

The herein-described swinging gate comprising a post, apivoted barrevolubly mounted thereon, brackets extending horizontally from saidpost, a gate mounted to slide vertically on said pivoted bar, a lever toraise and lower the gate, a curved bar 10 secured to the front end ofthe gate and extending backward and upward above the gate and pivotallyconnected to said lever, a latch-bar adapted to be simultaneouslyretracted when the gate is opened, a lever connected to said latch, alatch-post, pivoted gravity-operated keeper-plates arranged on said postto receive the end of said latch-bar when the gate is in closedposition, a spring 19 secured to said lever 17 and flexible connectionsbetween said bar 17 and the operating-lever for opening and closing thegate, substantially as described.

In testimony whereof We have hereunto set our hands in presence of twosubscribing Witnesses.
